Which title was Ada's husband given in 1838?

Which title was Ada's husband given in 1838? Earl of Lovelace. Ada’s husband, William King, was created Earl of Lovelace in 1838 and also received the subsidiary title Viscount Ockham.

William had married Ada Byron in 1835, when he was William King, 8th Baron King. His elevation to an earldom changed Ada’s formal style: she became the Countess of Lovelace. The title was selected because Ada was descended from the extinct Barons Lovelace.

This is why “Ada Lovelace” is not her birth name. She was born Augusta Ada Byron, later became Lady King through marriage, and then became the Countess of Lovelace after her husband’s promotion. Her son, Byron King-Noel, later inherited the earldom.

The title was a British peerage created during Queen Victoria’s reign. It was not a title inherited directly by Ada during her husband’s lifetime, although she was conventionally identified by the feminine form of his new title.
